½ cup unsalted butter, softened
1 cup brown sugar (packed)
1 cup granulated sugar
2 large eggs
1½ cups all-purpose flour
1 tsp baking soda
½ tsp salt
1 tsp ground cinnamon
¼ tsp ground nutmeg (optional)
1 tsp vanilla extract
For the Coconut-Pecan Topping:
6 tbsp unsalted butter
½ cup brown sugar
¼ cup whole milk or cream

½ tsp vanilla extract
Instructions
Step 1: Soak the Oats
-
Combine rolled oats and boiling water in a bowl.
-
Stir and let sit for 15–20 minutes until the oats absorb the water and soften.
Step 2: Preheat & Prep
-
Preheat your oven to 350°F (175°C).
-
Grease a 9×13-inch baking pan or line it with parchment paper.
Step 3: Make the Cake Batter
-
In a large bowl, cream together softened butter, brown sugar, and granulated sugar until light and fluffy.
-
Add eggs and vanilla extract, and mix until well combined.
-
Stir in the soaked oats.
-
In a separate bowl, whisk together flour, baking soda, salt, cinnamon, and nutmeg.
-
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Step 4: Bake the Cake
-
Pour the batter into the prepared baking pan and spread evenly.
-
Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean.
-
Place the cake on a cooling rack while you prepare the topping.
Step 5: Make the Topping
-
In a saucepan over medium heat, melt butter.
-
Stir in brown sugar and milk. Cook, stirring, until the mixture is smooth and begins to bubble.
-
Remove from heat and stir in coconut, pecans, and vanilla extract.
Step 6: Top & Broil
-
Spoon the topping evenly over the warm cake.
-
Place under the broiler for 2–3 minutes until bubbly and lightly golden—watch closely to avoid burning.
-
Let cool for at least 10 minutes before slicing and serving.
Notes
Use Old-Fashioned Oats – They give the cake the best texture.
Don’t Overmix – Stir just until ingredients are combined to keep the cake tender.
Watch the Broiler – The topping can burn quickly, so keep a close eye.
Make Ahead – This cake tastes even better the next day as the flavors meld.
Add-Ins – Stir in raisins or chopped apples for extra flavor and moisture.
